Rattle above 3K rpm

[aaron_]

Bought my 2005 FZ1 a couple months ago. I have noticed a rattle sound above 3k here lately. Almost sounds like pebbles rattling around. It sounds like it’s coming from the top of the engine but I can’t figure out exactly. Anyone have ideas?

That sound is usually attributed to the cam chain tensioner...

FZ1OA may have more info on that subject...
